NRC Clinton Special Evaluation Team Report Mr.
Larry Haab Chief Executive Officer Illinois Power
Company 550 S. 27th Street Decatur, IL
62717 Dear Mr. Haab This letter forwards the
Special Evaluation Team (SET) report for the
Clinton Power Station (CPS). The decline in
performance of CPS became apparent to the NRC in
September 1996. This trend was documented in a
letter to you dated January 27, 1997. At the June
1997 Senior Management Meeting, the NRC decided
that CPS should remain on the list of plants with
a declining performance trend and that a

The ISA, conducted from August through October
1997, identified significant weaknesses in
operations, engineering, maintenance, and plant
support. Examples of these weaknesses occurred in
conduct of operations, management and supervision
of operations, performance of system engineers,
control and understanding of the design bases,
maintenance work scheduling and work processes,
and radiation protection. In addition, the ISA
identified a number of weaknesses in the barriers
to prevent safety problems that are not typical
of facilities with a strong nuclear safety
culture. These weak barriers were found at all
levels of management associated with CPS and were

Power said it will purchase at least 75 percent
of the Clinton plant's electricity output through
